摘要：
Disclosed is a method and an auto-injector for administering a medicament. The auto injector comprising: a housing； a cartridge receiver configured to receive a cartridge comprising a first stopper； a drive module coupled to move a plunger rod between a retracted plunger rod position and an extended plunger rod position, the plunger rod being configured to move the first stopper； a resistance sensor configured to provide a resistance signal indicative of resistance against movement of the plunger rod； and a processing unit coupled to the drive module and to the resistance sensor. The processing unit being configured to: control the drive module to move the plunger rod towards the extended plunger rod position with a plunger rod speed； determine plunger rod position； receive the resistance signal； and control the drive module to adjust movement of the plunger rod if the resistance signal is indicative of resistance against movement of the plunger rod above a high resistance threshold, wherein the high resistance threshold is based on the plunger rod position.
